随着我国铁路向着高速、重载、大功率方向大力推进,对端齿联结提出了更高的要求。要求其在有限的空间内实现高转速运转和大扭矩的传递。通过分析,得出各种运行工况下圆弧端齿联结的齿形应力分布规律以及圆弧端齿齿根应力和齿面接触应力的变化规律。 As China’s railways toward the high-speed, heavy load, high-power direction to promote the end of the tooth put forward higher requirements. Requires it in a limited space to achieve high-speed operation and transmission of large torque. Through the analysis, the law of tooth stress distribution and the variation rule of tooth root stress and tooth surface contact stress at circular arc end under various operating conditions were obtained.
